Cup and Ring Marks / Rock Art

Fieldnotes

Visited the site after going to the duddo stone and the battle stone. It was only after leaving the site travelling home and arriving in Millfield I realised how easy it is to get there.
Never got down to the waterfall as the fiancee wanted to go home. All this around her and she wants her tea.
Anyway, what a place. The ditches are big and a puzzle. The rock art on the stone is in very condition and plenty of it.
I have got photos to put on, but I have not got photoshop after wiping my drive before christmas and I cannot find the disk.
At the back of the monument, is that a water channel or where rain water has worn away at the stone.
Also is that a grave at the back?
